Thanks Cando, so much for the census information.
I didn't have Hanna's parents names when I was looking for Ingram's in Beccles. I do now, thanks to the kind person with the public tree.
I have also purchased Mary Ann's birth certificate only to find that it is only the Baptism record the same as the kind person with the public tree had attached to her. So no extra information there.

Edward was baptised on the same date, and is on the same baptism record.
Aunty E said over the weekend that she believes the DAVIDSON's were whalers, and she has been to the museum in Eden NSW with her cousin. So I am now looking for James using this information as a starter, but I do remember that family stories can be just that - a story.
Oh well, I think I have now found every ancestor that came to Australia from overseas
Thank you again for your help, Cheers, Ted
